Dear Experts,
Recently I have faced a strange issue in Dynamics CRM 2015 On-Premise instance.
Functionality:
We have a custom workflow that schedule to run daily, this will update an Entity1 record status.
On Entity1 Status update, we have plug-in to update Entity2.
On Entity2 Status update, we have plug-in to update Entity3.
On Entity3 Status update, we have plug-in to update Entity4 (Master Entity).
Basically, 3 level of Plug-ins. All these plug-ins registered as Synchronous.
In this scenario, we have only 1 Master record and all the 55 records are trying to update this one record.
Issue:
Custom workflow ran on 55 records at a time, first 15 records were completed as successful and other records went to waiting stage. Server Event viewer logged different types of errors and some of the errors summary as below:
Initial Error:
ServerName; CrmAsyncService.exe (1908); ACF75705; execution time:00:01:25.4526639/ServerName; Microsoft.Crm.Sandbox.HostService.exe (2764); D1FF8028; execution time:00:01:25.4526639; Plug-in Name, Version=1.0.0.0, Culture=neutral, PublicKeyToken=cd55c642b9a72843:Plug-inName/ServerName; Microsoft.Crm.Sandbox.WorkerProcess.exe (4504); 539A2153; execution time:00:01:04.9520100/-

Note: I have googled the issue and some blogs suggested to declare the "Server" object at Execute function level instead of Class level. I have verified, all the Plug-ins steps are registered at Execute function level only.
Kindly let me know what is causing the error?
